Hi all , quick question, a customer of mine has a 2016 reg discovery 4 and I put my IID TOOL on it today to clear its faults . It has one fault that won't clear and thats U0102-00, communication with transfer case module. I couldn't see how to select low range so couldn't check to see if it worked. I assume all disco 4 s have low range so could some one point me towards where the switch is please ? 2015 4.4 AB

Should be the same as a RRS, so a small rocker switch on the panel below the gear selector dial, drivers side I think. The opposite switch is the suspension raise/lower

@Andy s , thanks for the prompt reply , when sitting in the drivers seat there is a panel in front of the gear selector which has four terrain modes on top and then the lower / higher rocker switch with hill desent and the Eco button for the start stop but no switch for low range that I could see. I'm not sure of the spec hence why I wondered if they all had low range . 2015 4.4 AB

Yep they all do have low range, at least I’ve never heard of one without....

Has someone replaced that switch with one out of an ewok or disco sport?? Disco sports don’t have low range!

Switch looks like one of these depending. But I would suspect the bottom one....

It is the right hand rocker switch...

Its what I call the older shape so I thought it was a D4, thats my excuse and I'm sticking to it.  2015 4.4 AB

Thanks to Northern monkey a good search has revealed that low range was an option on D5s , if this is correct could that explain the loss communication fault code ?? 2015 4.4 AB

There's a D5 area on the D3 / D4 forum. You could ask there? 2016 Skoda Octavia VRS Estate
